Water Pressure Flashcards
What causes the flow of water out of a tank?
Differences in water pressure
The pressure at any point under the water increases with…
the height of the water above it.
What is true about pressure?
It doesn’t point in any particular direction.
The pressure only depends on…
the height of the water level above the end of the tube.
Pressure in a barrel doesn’t depend on…
the weight of the water inside it, only on the height of the water above it.
What happens if a barrier in a pipe that has a net force on it is removed?
Then the flow through that pipe would be in the direction of the net force.
What is true about water’s volume?
Water maintains its volume as it flows.
Where must water flow to speed up?
It must flow from a region of higher pressure to lower pressure.
Where must water flow to slow down?
It must flow from a region of lower pressure to higher pressure.
